Designed for water quality experts, the advanced Hach HQD laboratory meters take the guesswork out of measurements. All HQD meters feature an advanced yet simple user interface that does not require manuals or training to operate. HQD meters connect with smart Intellical electrodes and automatically recognize the testing parameter, calibration history, and method settings to minimize errors and setup time.

Choose from 3 models, including the dual-input HQ440D and single-input HQ430D versions. These multi-parameter meters offer the ultimate in versatility and redundancy - perfect for budget-constrained laboratories.

Interchangeable Intellical probes for measuring pH, Dissolved Oxygen (DO), Conductivity, Total Dissolved Solids (TDS), Ammonia, Ammonium, Fluoride, Nitrate, Sodium, LBOD, and RedOx (ORP).

From basic pH meter with superior price position up to multi parameter solutions with optional bi-directional PC connection: Sension+ offers complete solutions for any kind of electrochemistry measurement tasks. Each system is designed for a wide variety of applications and comes complete with everything you need to start testing. The Sension+ offers a cost-effective complete package option to begin testing quickly pH, ORP, Conductivity, Total Dissolved Solids (TDS) and Dissolved Oxygen (DO), as well as a bundle of Ions by ISE such as Sodium, Calcium, Fluoride, Nitrate and Ammonium.

All Sension+ benchtop kits are supplied with a laboratory meter, probe, integrated probe stand and stirrer, carrying case and all required accessories, making it simple to grab the kit and begin testing immediately.

sensION+ Field Kits work as complete mobile measurement stations with ergonomic, lightweight design and IP67 protection. Screw-on calibration tubes simplify on-site calibration and minimize consumption of standard solutions. It is designed as complete field solutions – from single parameter pH meters up to multi-parameter systems for simultaneous measurement. The Sension+ offers a cost-effective complete package option to begin testing quickly pH, ORP, Conductivity, Total Dissolved Solids (TDS) and Dissolved Oxygen (DO), as well as a bundle of Ions by ISE such as Sodium, Calcium, Fluoride, Nitrate and Ammonium.
